Human blastoids are the first human embryo models that are derived from cells cultured in vitro and that have all the founding cell lineages of the fetus and its supporting tissues.

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

The generation of human blastocyst-like structures (blastoids) from human pluripotent stem cells paves the way for new contraceptives and more IVF success.

Analyzing embryo movements in uteruslike environments could offer clues to improving the success rate of in vitro fertilization ...

Embryo models could help scientists understand stem cell differentiation, the development of organs, and how defects arise. Scientists imaged this embryo model after eight days in culture. It consists ...

The work could provide important new insight into human development and miscarriage, but also raises thorny questions about research into embryo-like models.

Sixty percent of miscarriages are caused by the failure of an embryo—the developmental stage before a fetus—to implant in the woman’s uterus. Part of the problem is that researchers have no idea how ...

Together, our results indicate that the critical remodelling events at this stage of human development are embryo-autonomous, highlighting the remarkable and unanticipated self-organizing ...

Scientists recorded in 3D and in real time the exact moment a human embryo implanted itself in an artificial uterus, opening ...

Unique insight into development of the human brain: Model of the early embryonic brain Date: May 26, 2020 Source: University of Copenhagen The Faculty of Health and Medical Sciences Summary: Stem ...

In a ground-breaking experiment, researchers successfully created the first human-monkey chimera, with huge implications for medical research.

Embryonic morphological development is delayed in live pregnancies ending in miscarriage, according to a prospective cohort study from the Netherlands. Among over 600 singleton pregnancies, those ...
